IMPROVEMENT IN REFRlGERATOR-BOXES.

Specification forming part of Letters Patent No. 200,982, dated March 5,1878; application filed January 19, 1878.

To all 'whom it may concern:

Beit known that I, GEORGE D. OUNLIFEE, of Brooklyn, in the county ofKings and State of New York, have invented a new and useful Improvementin Refrigerators, which improvement is fully set forth in the followingspecification, reference being had to the ac,- companying drawing, inwhich- Figure l represents a horizontal section of my refrigerator inthe line ao x, Fig. 2. Fig. 2 is a vertical section in the line y y,Fig. 1.

nSimilar letters indicate corresponding parts.

My invention consists in the combination, in a refrigerator box or casethe sides of which are detachable from each other, and constructed withdouble walls, of catches which are located in said double walls, andserve to hold the sides together, with vertical rods for operating thecatches, so that the refrigerator box or case can be taken apart tofacilitate transportation of the article, and at the same time thecatches and their operating-rods are protected against injury.

In the drawing, the letters A A designate the sides of my box, and B isthe bottom thereof. I4 construct the sides A A with the usual doublewalls, 'and make the same detachable from each other. The letter Cdesignates catches, serving to hold the sides of the box together. Thesecatches have the form of hooks, and are arranged in sets, each set beingpivoted in uprights I), which are placed in the opposite ends of thesides A, and between the double walls composing such sides, as shown inFig. 1.' Said catches, moreover, are arranged to project on the in nersurface of the sides A, to which they are applied, and engage with slotse formed in metallic plates, which are secured to the ends of the sidesA.

Each set of catches, or those in each of the nprights D, are placed in acorresponding verticalV plane, and connected to a vertical rod, F,passing through or alongside of the respective upright.

The lowermost catch C of each set is connected to the lower end of therod F, and is subjected to the action of a spring, g, which has atendency to force the said lower catch, as well as the rod F and theupper catch, downward, thus locking both catches.

The upper ends of the rods F are ush, 0r

nearly so, with the upper edges of the sides A or A and to such ends ofthe rods are connected rings h, by which they can be conveniently pulledupward.

To a suitable portion of each of the sides A or A is secured a sill, I,and on these sills I place loosely the bottom B.

In putting the parts of my box together, I rst connect three of thesides A or A', then slide the bottom B into place, and then attach theremaining or fourth side, While, for the purpose of detaching the parts,it is only necessary to disengage the catches O.

By making the parts of my box detachable from each other, itstransportation is materially facilitated, while by arranging the catchesin the manner shown they are not liable to become injured, and areconcealed from View.

In connection With my box I use a detachable lid, J, and a removableice-pan, K, this pan, moreover, being of such a size that an air-spaceis formed around it, as shown. From the bottom of the pan K projects adischargepipe, l, which telescopes with a pipe, m, rising from thebottom of the box.

In my box are also arranged grates N, which, as well as the ice-pan K,are supported by detachable slats o, the pan being also partly supportedby flanges formed on its upper edge.

One of the sides A or A is provided with a channel, p, for thecirculation of air, and between the double walls composing each of saidsides I place a illing of hair, felt, or any other suitable material.

What I claim as new, and desire -to secure by Letters Patent, is-

The combination, in a refrigeratorbox the sides of which are detachablefrom eachother, and constructed with double walls, of catches which arelocated in said double walls, and serve to hold the sides together, andvertical rods for operating the catches, substantially as shown anddescribed.

In testimony that I claim the foregoing I have hereunto set my hand andseal.
